I believe thats because RB and CS have cavities that essentially establish the operating size, because they work at a given frequency.
That makes sense You have to go
to a different technology method to reduce its size, like the new Symmetricom CS oscillator. Still overall pretty darned amazing in size and power consumption. (Still waiting for the time-nuts offer of $100 each. Limited time offer call before midnight. Shipping and handling included) So at this time it would not be possible to equal the size or power of a typical TCXO these days. 1/4 dip stuff. Though we have given you answers you had not ever really stated what you needed to accomplish. Regards Paul WB8TSL
I've bought an amateur radio transceiver - Kenwood TS-940S. This has a 20 MHz crystal osciallator (not 10 as I stated before), but it was optionally available with a 20 MHz TCXO, called SO-1 which sat on a small (how small?) circuit board. But these TCXO's seem to be like rocking horse dung, so I wondered about putting my own TCXO on a board. Then the idea of perhaps using a rubidium hit me.
Some enterprising sole is selling on eBay a circuit board which replaces the SO-1, and has a 10 MHz reference input. But of course that means you need to rely on having the external reference. Having it built in would be nice, but I don't think there's enough room.
Perhaps an OCXO might be practical - better than a TCXO, but not as big as a rubidium.
